访问2010年：加入三个表，未知错误

Question

我想在SQL查询中连接MS Access 2010中的三个表。

SELECT Track.trackName, TrackIsGenre.genre, ContainsTracks.albums 
FROM Track 
INNER JOIN TrackIsGenre ON Track.trackName = TrackIsGenre.track 
INNER JOIN ConstainsTracks ON Track.trackName = ContainsTracks.tracks 
WHERE genre = "Rock" 
ORDER BY trackName ASC; 

我搜索了网络，据我所知，这应该是它。我可以加入两张表没有问题。我得到的错误是：“在查询表达式中出现语法错误（缺少运算符）”，并突出显示了两个INNER JOIN。

任何帮助将不胜感激。

添加一个括号你第一次参加，（，这是大多数RDBMS可选）

SELECT Track.trackName, TrackIsGenre.genre, ContainsTracks.albums 
FROM (Track INNER JOIN TrackIsGenre ON Track.trackName = TrackIsGenre.track) 
     INNER JOIN ConstainsTracks ON Track.trackName = ContainsTracks.tracks 
WHERE genre = "Rock" 
ORDER BY trackName ASC;
